The Angola data resides in 1 book, 'Estudo Meteorologico de Angola' (C/fe AX1). In these summaries, definitions are as in the above. This book contains graphs of annual surface weather data for Angola from 1879 to 1915. Graphs contain the following data: annual mean pressure, temperature, humidity and vapor pressure; annual mean maximum and minimum temperature; and annual absolute maximum and minimum temperature.

These books are part of the foreign meteorological data collection held by the NOAA Central Library in Washington, DC. Information in this collection dates back to the 18th century for daily, monthly, seasonal, and annual tabular summaries, and the 19th century for weather maps. These data are the result of foreign exchange agreements, but the collection has not been updated since 1983.
